ideally, I would like you to save the file that is currently there somewhere else. delete the original log file, then execute the installer again. it should generate a clean representation of the error.

I deleted the Adobe Application Manager (by throwing it into the trash) from the Utilities folder because I thought it didn't do anyhting, but the After Effects installer checks for the application and if you don't have it, then the installer will fail

Hi. I see this thread is old...last post is july 2010. However, since I just had a similar issue and since a google search brought me here, i figure id share my info with other who my hit this too...

i have os x 10.7 and am trying to install cs5.5 master collection. i kept getting the installer failed to initialize error.

by looking at the PDApp.log, i saw an error and fixed the issue causing the error...

my issue was when launching Install.app, it looks for ~/Applications and creates a folder "Adobe" in it. I had an alias in my home dir and the log showed the installer didnt see it as a valid directory.

by removing the alias, the installer then created the folder "~/Applications/Adobe" for me. However, since it created an empty folder named Applications, separate from the actual /Applications dir, this was not acceptible.

So, if i right click on /Applications and hit "Make alias" and move that to my home dir...same issue.

But, if i open Terminal.app and type "sudo ln -s /Applications" the seemingly same type of alias or "symbolic link" is created, but instead the installer see the dir as valid, and the install went flawlessly.

So, it sounds like a permissions issue. Since you created the alias via terminal using root or su privileges, it would appear that you user account isn't creating the appropriate privileges for that alias. Did you check the differences between the alias made via terminal and the alias made via the gui?

Thanks for posting this solution. I am working from Windows 8 Pro and had to reinstall Dreamweaver CS5.5. My installation would not initialize and provided the same errors. After installing Adobe Application Manager CS6, Dreamweaver installed beautifully. Thanks.
